screenshot of issue

Set iPad to Dark mode. Go to Safari, then go to google.com and tap or click the app grid icon in the top-right corner. Observe the scrollbar (A.K.A scroll thumb) is not there or not visible. Now set the iPad to Light mode and try it again, observe the scrollbar is there/visible. Attached is a screenshot (I added the red arrows pointing to the scrollbar/scroll thumb just so it's extra clear what I'm talking about)
